MOLD FOR CONCRETE WALLS.

Specification of Letters :Patent Patented Mar.. 29., initd.

Application filed February 26, 1908. Serial No. 417,941..

To all whom 'it may concern:

'Be it known that I, HARRY J. KIMMEL, a citizen of the United States',residing at lVenatchce, in the county of Chelan and State of Washington,have invented new and useful Improvements i'n Molds for ConcreteI'Valls, of which the following is a specification. 4

This invention relates to molds for concrete walls, the object of thevinvention being to provide, simple apparatus in the nature of asectional mold adapted to be added to from time to time as occasionvdemands for the purpose ot' extending the molded wall and turningcorners or forming otfsets therein, the inold being Inade u p of aseries of sections constructed to have an overlapping and interlockingengagement with one another, the said sections being adjustably lattercombined with gaging members which serve to hold the mold sections atthe proper distance apart to admit of the torination of a wall betweenthem; also permitting the relative adjustment of the mold sections andtheir angular' disposition with relathe particular shape ot the wallbeing formed.

vWith the above and other objects in view, the invention consists in thenovel lconstruction, combination and arrangement of partsclaimed.

In the accompanying drawings :'ligurc l is an end view ot opposite moldsections, the supjmrting bars thereotl and the means for gaging thedistance between the mold' sections; also the means tor adjusting theangularity of said sections. Fig. 2 is an outside or rear elevation ofone oi the mold sections7 showing the connection of the supporting barstherewith. Fig. 3 an enlarged detail vertical cross section through thesame7 .showing the. connection between the same and one of the boltswhich secure the section to the adjacent supporting bar, Fig. 4 is adetaithorizontal section illustrating the overlapping joints between thesections and one ot the clamps. Fig. 5 is a. 'detail horizontal sectionshowing a corner joint between the sections -and the clamping meanstherefor. Fioj. is a similar view showing the joint at the. inner anglel between contiguous sections.

The manner in which a wall is .formed by the mold of this invention isillustrated in Fig. l in which l designates a partially constructed walland 2 oppositely located mold sections which it will be` observed arear- .anged ata distance apart equal to-the thickness of the wall 1, thewall being termed by introducing concrete in a plastic condition betweenthe opposite mold sections il.

The mold sections. as shown in 1 l, are connected to and supported byoppositely arranged mold sujporti bars f3 'which are connectedadjusialny to the mold sections by means vherei natter descrihed7 thesaid bars 3 extending upward a ein able distan .e above the moldsections where t are connected to and braced by ineens et upper andlower gage bars l ando, rcspectively. The upper gage bar is providedwith a plurality of rows ot holes i adaptetto receive pins 7 which passalso through holes in the bars 3 and thereby prevent rela tive movementbetween the upper ends ot' the supporting bars 3,4 two or more rows ofholes heilig provided in order tornialte, allowance for a tineadjustment otl the distance between said slipporting bars. The lower baris provided for a portion of its length with holes'S correspoinling inarrangen'ient with the holes (S above described and adapted to receive apin 9 which passes through the adjacent supporting bar 3. The oppositeend portion of the bar 5 is provided with a series ot slots or notches10 which open ont at their upper ends and incline outwardly toward theirlower closed ends as seen in Fig. l, the said ,slots being adapted toreceive the trunnions or pivot ll ot a cam lever 12 which is arrangedjust outside of the adjacent supporting bar 3 as shown in Fig. l, andacts as a cam lock between said supportinfc` ba" and the lower gage bari?. rlhe cam lever l2 is used to ltorce the opposite mold` sections 2towardv each other and into closed engagement with the portion of thewall which has been coinpleted as illustrated in Fig. l. It will also beobserved in Fig. l, that one or both of the bars 3 ,may be swung outwardto an angle as indicated by dotted lines to correspondingly position themold section carried thereby in order to give a 'liare to one or bothsides oi. the wall l as also indicated by dotted lines in said figure.It may here be noted that the inner molding faces of the. sections 2 maybe either plain or iigured or given any desired ornanientation in ordernected a cam lever 1'? adapted to bear to impart a correspondingornamentation to the adjacent surfaces of the wall under construction.

Each mold section, as shown in Figs. 2

and 3, comprises a face plate 13, and margi-VVV nal frame pieces 14 otangle iron which' extend along the four edges of the face plate 13 andare riveted or otherwise fastened thereto as shown. Along one end of theplate 13, the angle iron trame piece is set slightly inside of theextreme edge of said plate as shown in Fig. 4, while at the opposite endthe angle iron frame piece is made to project a corresponding distancebeyond the face plate 13 as also shown inthe same Fig. 4 thus makingprovision for an overlapping joint between the contiguous ends of twoadjoining sections, which are then fastened firmly together by means ofa clamp comprising a U-shaped. body 15 to one end of which is connecteda. pivoted jaw 16 adapted tobear tiatwise against one ofthe angle irons,while to the opposite end of the clamp body there is pivotallyconagainst the opposite angle iron as shown in Fig. 4 to bind the twoangle irons closely together and hold the mold sections in rigidrelation to each other.

In forming the outer corner of a wall, the. sections are combined asshown in F igf' in which the two sections are shown as meeting at aright angle to each other, one of the angle irons overlapping theextreme edge of the face plate of the adjoining section, while the twosections are held'together by means of a clamp the same as thatillustrated in Fig. 4 but having in addition thereto a corner clip 18embodying a hook 19 which fits around the outer edge of one of the angleirons and a lip 2() at its opposite end which is engaged by the :head ofthe cani lever 17. .In this way the Outer corner oi the mold is formedand the abiitting mold sections held firmly in engagement with eachother. lhe inner .corner of the wall is formed by abutting sectionsshown disposed at a right angle to each other `as seen in Fig. 6. .lnthis case, however, an ade ditional double angle plate 21 is employechthe same having 'a rabbcted offset 22 to receive the projecting edge ot'the faceplate of one section, and an inturned iange 23 adapted to engageover the corner ot' the angle iron-of the adjoining section, the doubleangle plate 21 thus having an overiapping and interlocking engagementwith the mold sections.

ln order to provide for the adjustment of j the mold sections upon themold' supporting g bars 3, each section is provided with arallel slottedor shouldered bars 24 an 25 l extending along the back and lengthwiseithereof as .shown in Figs. 2 and 3, each of said bars being providedwith a longitudinal channel 26 sufficiently wide to receive the heads 27of the bolts 28 which secure th sectiontorthe adjacent mold suppering/bar 3( IThe outer 'wall of the journal portion of each bar isprovidedzwith/a longitudinal slot 29 along Which/the body or shank ofthe bolt 28 is movable for the purpose ,of adjusting the mold supportingbars lengthwise of thesection which they support, as clearly indicatedin Fig. 2.

30 designates a bridge plate or washer adapted to straddle a pair ofbolts as shown in Fig. 2 which bolts lie at opposite sides of thesupporting bar 3 whereby a iirm connection is obtained between eachsection and the supporting bars thereof, While at the 'same timeproviding for the relative adjustment of said members.

The adjustment between the mold sections and the supports thereforenables the sections to be set in proper relation to each other and alsopermits the sections to be set up or down to bring themy to the requiredelevation.

Having thus described the invent-ion, what is claimed as new, is

- l. ln a molding apparatus, the combina- -tion of oppositely arrangedmold sections,

mold supporting barsV connected therewith,

VsetsV of parallel frage bars located at (liderent elevations an havingan adjustable connection with such supporting bars above the moldsections, one set of gage bars being provided with transversely Valinednotches at one end, and a clamping device consist-ing of a detachablecam leverhavinfrtrunnions projecting from opposite sides Jthereof andadapted to tit Ainto any opposite pair of notches in the notched gagears and operating against one of the mold supporting bars to crowd themold sections toward each other.

s 2.V In a molding apparatus, the combination of adjoining angularlydisposed corner forming mold sections, angle iron frame pieces extendingvertically of the abutting edges ot" the mold sections, a corner clipprovided with a hook shaped flange embracing one of the flanges of oneof the said trame pieces, and a clamp adapted to engage said corner clipand the adjacent frame piece and hold the adjoining mold sectionstogether, said clamp embodying a U-shaped body and a cam lever.

ln testimony whereof I affix my si gnature in presence of two witnesses.
